To all when@ t may concern:

Be it known that I, FRANK LYSTER, a citizen ofthe United States, residing at Philadelphia,

in the county of Philadelphia' and'State ofl Pennsylvania, have invented certain new and .nseful Improvements in Ventilating Sash?` Bars; and I do declare the following'` tobe la full, clear,l and exact descriptionof the invention, such as willl enable otherss'killed in the art to which it appertains to make and use the same.

My invention is an improved Ventilating sash-bar adapted for use `for skylight and other sashes; and 1t consists in the construction and arrangement of devlces herelnater described Une objet of my invention is to effect improvemcnts y1n the construction of sash-bars,

-whereby the same may be made of sheetmetal and sol e'ectuallybraced as to render the isamei exceedingly strong, while being light and adapted to be manufactured very cheaply.

lA further object ofmy invention is to prow vide a Ventilating sash-bar.` made of a blank loi' sheet metal bent to form a cap, a hollow web depending therefromand over-hung thereby, and a chamber below the web, forming means for bracing the saslnbar and alsoform- A further object of my invention is to prof vide a Ventilating sashbar having ventilating-openings and means to uncover or vclose them at will. Y

A .further object of my invention is to combine with thesash-bar al joint sheet to bear on the outer and inner sides ofl the glass and to bear againistthe web and supporting-shoulder of the sash-bar-e- I v, .y A furtherobject ot' myinvention is lto oombine with asash-bar having a cap and hollow web communicating therewithand a chamber communicating with the webf and forming a support for the glassa stiHening-bar in the cap, web, andchamber.

A further object of my invention, is to provide a ventilatingsash-bar with` a shutter of novel construction forv uncovering and clos- Ing the ventilatimq-openings iii the sash-bar Aat will. f

In the accompanying drawings,l Figure lis a transverse sectional View of a Ventilating sash-bar embodying my improvements. Fig.

2 is a detailelevation of the same withl parts- -broken away` to show interior constructions. Flg, 3 is a vert1cal.-transverse sectional View showing amodified form Of my improved ven-l ytilating sash-bar. Fig. ,4 is a transverse sectional. view of another modified form'ot` my fed forms of my invention.

My improved sash-bar isl made of sheet metal, preferably zinc, galvanized iron, copper, or the like, which in the form shown 1n Figsgl and2 `is composed ofa pair of sheet- These sheet=blanks are united by the joint then bent orinclined outwardlyor downwardly, as at 2, then bent 'inwardly to form the overhangs 3, having Ventilatingfopenings 4t, then bent downwardly at 5 to form the side walls of a hollow web 6, then bent out'- wardly to form supporting shoulders y7, then Idownwardly and inwardly to form the downwardly-converging sides 8 of achamber 9, ,under and communicating with the hollow web, and then'outwardly to form gutter-ianges 10,

'- the outer ends ot' which are upwardly and outwardly inclined, as at 11.

The inclined 'sides8 of thechamber 9 are provided with ventilatingf openings 12. .The portions 2'3formahollow cap 13 above and communicating'with the hol. low web, which cap projects laterally from opposite sides of. the web. A cover 4plate or sheet 14 is placed under the gutter-anges 10 and connects them together and has its edges upturn'ed 4and bent around the edges l11 of ,the

.gutter-anges, as at 15,

on the shoulders 7 "of-the chamber 9 and rlhe sheets or plates 16 ofy glass or other material are supported 90.

against the sidesof the web 6.. A jointlsheetl of lead, Zinc, or other'sutable sheet metal (indicated atV 17) bearsA on the glass, as at 18, is" then bent upwardly or outwardly'to extend therefrom, as at 19, is then reversely; bent and doubled,- as at'20, to bearagaxnst one side Iof the web vand'to extend past the edge lof .the glass, and is then bent outwardly at 2l to bear'v between fthe inner side-of the glass andthe supporting-shoulder 7 of chamber-9, the .eX-

Ioo

treme edge of the, joint-sheet being bent, as at 22, to bear against the side of the chamber 9. It will be observed by reference to the drawings that the joint-sheet is overhung by the side portions of the cap 13, which serves to prevent rain 4from entering the joint between the joint-sheet and the web, and that such rain-water as it enters the joint-sheet and the glass is caught by the gutter-flanges 10.

To enable the Ventilating-openings 12 in the'downwardly-converging side walls of the chamber 9 to he covered or opened to any desired extent, I provide a'shutter 23. In the .form of my invention shown in Fig. 1 this shutter is made of sheet metal bent to form downward lyconverging sides 24 and is placed in the chamber 9 so that its vflownwa'rdly-converging sides bear on and are supported by the downwardly-converging sides 8 of the saidrchamber. This shutter is provided with openings 25,l adapted to register with the 'ventilating-openings in the chamber, and by moving the shutter endwise, said Ventilatingopenings may be uncovered or closed to any desired extent, as will he understood. The side or wall of the chamber is provided with a slot 26, in which operates a button ,27, that is'secured to and projects from the shutter,

the said button lcoaeting with the-slot to limit the movement of the shutter. A spring 28, which vis here shown as a coiled retractile spring, is attachedto the shutter and to the wall of the chamber 9 at a suitable point, and its ,function is to normally move the shutter to the position required to close the ventilating-openings. Any suitable means, such as cord engaged by a direction-pulley, may be employed to move the shutter in the reverse direction to uncover the Ventilating-openings. I dol notlimit myself in this particular'. The shutter may be. coextensive in length with the sash-bar or it may be formed of sections either independently movable or simultaneously movable, asmay be preferred. I do not limit myself in this particular.-

In the modified form of my invention shown in Fig. 3 I employ a stiifening-bar 29, which is placed in the sash-bar and extends through the ca p, web, and supporting-chamber of the sash-bar and is disposed centrally therewith and spaced from the sides of the web. This stiffening-bar may be made of any suitable metal or other material, is removable from the saslrbar, and adds greatly to the strength thereof, as will be understood. In this form of my invention I employ a pair of ventilating-shutters 30, which are operable independently of' each other, are placed in the venti? the glass.

dow-sash, whether of metal or wood. ln this form the cap 32 is formed integrally with the web 33, the walls of the latter being doubled, as at 34 35, and the outer walls 34 being bent to form anges 36 to lie on the outer sides of Ventilating-openings 37 are made in the overhang-s 38 of the cap. The inner cap 39 is formed separately, is bent from sheet metal, and provided with hollow flanges 40 and supportin -walls 41, which bear against the inner side t' the glass. The inner portions of the walls of the web are secured in the hollow fianges, and the portion 42 of thc inner cap between the hollow flanges is provided with longitudinal slots 43. one near each end of the bar, only one of said openings being here shown. The shutter 44 is substantially U-shaped in cross-section, lies against the inner side of the portion 42 of the inner cap, and is disposed between the walls of the web. The shutter is longitudinally movable by means of knobs 45, the stems of' which operate in the slots 43, and is provided with velitilating-openings 46, which bythe'movement of the shutter may be moved into or out ot' register with similar openings 47 in the portion 42 of the inner cap. The openings 46 are covered by wire-gauze 48 orother suitable foraminous material soldered to the inner side of the shutter, and the stems of the knobs 45 are screwed to nuts 49, which are also soldered to the'inner side ot' the shutter. prevents the passage of' sparks through the bar. as will be understood.

In Fig. 6 I show another modified form of my invention, in which the vent-openings 5() are in the sides of the cap 51.

In Fig. 7 I show another modified form of my invention, in which the web 52 is formed with the inner cap and the cap or head 53 is formed with flanges or web-walls 54, ywhich engage and are secured to the walls of the web. The cap or head 53 has lateral over- `hangs 55, provided with the vent-openings 56. In this form of' the invention putty (indicated at 57) is employed for securing the glass in place.

In Fig. 8 I illustrate another modified form of' my invention, in which the stiiening-bar 58 is provided at suitable intervals with rightangled lugs 59, secured thereto by bolts 60, which lugs bear under th'e shoulders 61 of the inner cap or chamber 62 and sustain the weight of the glass.

I do not desire to limit myself to either of the precise constructions herein shown and described, as it is evident that modifications may be made without departing from the spiritof my invention and within the scope of thc appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
